The most basic function of a car key is to unlock the vehicle and ignite it. However, with the continuous advancement of technology, the form of the key has changed dramatically, and the functions have become more and more abundant. Today's car keys have gradually changed from large to small, and even from physical objects to a piece of code that exists virtually.
The longest surviving rocker key
The appearance of the car key is much later than the birth of the car, in the birth of the car for a period of time, many people do not know how the car is started, the first stage of the key looks like no one knows, because the car at that time did not need the key to start. By 1913, Lewis Reed had started a car with a rocker, the first car key to start the ignition. This type of key still exists, and on some old tractors, we can still see the figure of the rocker key.
The Gospel of the Female Driver
With the development of the automotive industry, the style of the car is changing at the same time, and the car keys are also constantly innovating. After decades of development, car keys finally have the form of keys. In late 1940, Chrysler created the first mechanical key, which was like a door key used in everyday life.
It has a simple appearance, but it already has the ability to open and close the lock door, as well as the engine start function. In the past, more car keys with key forms were only the function of locking doors and windows. The birth of this key also brought the car into the era of electric start- After rotating the key, the motor is electrified to drive the gear meshing, thereby driving the crankshaft to rotate, which also achieves the purpose of starting. In the past, the bulky rocker key dissuaded many female drivers, and the lightweight mechanical key allowed petite women to have the ability to drive.
The first "core" of intelligence
After the mechanical key, there were more and more cars, but due to the relatively simple construction of the mechanical key, theft of vehicles became more and more common in the next 40 years. Chip keys were born in these 40 years, but in 1980, Ford introduced a remote control key to make the key more functional.
The key is placed inside a small circuit board, with central chip control, and there is also a remote control of the transceiver signal function. One lock key can lock 4 doors.
From 1980 to recent years, this type of key was the most common form, nothing more than to look more beautiful, and later introduced a folding key, which automatically popped out when pressed, which was designed to start the vehicle. When not in use, fold back to the edge of the key. Later, plug-in keys were also introduced, which had a one-button start function that ignited by a button by sensing whether the key was in the car. This kind of key usually does not use the mechanical key, and only in an emergency case, the key will be pulled out and used. In addition to the different ways of ignition, the remote control has more functions.
A smart key with a hundred flowers
Nowadays, more and more intelligent models have been launched, and smart keys have also come into being, and a variety of smart keys have blossomed on new energy vehicles. Although new energy is also a scooter, it can be regarded as a large electric toy, and there are many intelligent functions related to electricity.
The key is also no longer in the form of a key, it can be turned into a card, such as Tesla's card key, which can unlock the vehicle as long as it is sensed at the door.
It can also become an APP program on the mobile phone, as long as the mobile phone can control the ignition of the vehicle, etc., and even now there is an NFC function, even if the mobile phone is out of power, the mobile phone that supports the protocol can also unlock the starting vehicle.
In some new forces with high technology content to build cars, even more face recognition has been made into a vehicle starting method.
With the development of the car, the key is also ever-changing, but it is not far from its origin, and the ultimate purpose is to unlock the vehicle and control the car. However, in my opinion, although the mainstream is still chip keys, the future car keys will definitely tend to be intelligent, or rely on a single mobile phone to integrate the car key function.
